Reduce Size, Weight and Power of Telecommunication Payload and Satellite Command/Telemetry Subsystems
By the end of 2018,there were nearly 2,000 satellites in orbit, serving both military and commercial customers.Their missions span a wide range of functions including reconnaissance, surveillance, imaging, signal intelligence,meteorology, navigation and voice communications. With every new mission, customers increasingly want more functionality, which requires larger satellite payloads, and that forces manufacturers to increase the size, weight and power (SWaP) of their satellite command and telemetry systems.
This white paper discusses how using the ISL72814SEH 16-channel driver circuit IC and the ISL71841SEH multiplexer simplifies the design of next-generation telecommunication payload systems and satellite command /telemetry subsystems. Examining these components reveals that they reduce footprint size by up to 50%, while doubling the number of telemetry data inputs and command outputs. Also, we’ll discuss the basic operation of the command output circuit and its role in the overall telemetry system.
